Radioactive activity meter

Application Fields

The radioactive medical activity meter is a precision mi measuring instrument widely used in nuclear medicine and radioisotope measurement.

The probe adopts high pressure sealed well type ionization chamber, easy operation, fast and accurate measurement. Wide measuring range and automatic range conversion, automatic half-life correction. The computer communication software of the system can be operated with the activity meter on the Chinese Windows platform, and the measurement results can be stored and printed directly.

Instrument Characteristics

• Nuclear medicine commonly used nuclides 99mTc, 131I, 67Ga, 201T1 can be measured

• In vivo nuclear medicine treatment nuclides 153Sm, 90Y, 186Re and positron nuclides 18F, 15O, 13N can be measured

• Measure 125I solid irradiated radioactive seed sources

• Users can build their own nuclide library according to their needs, and the capacity of nuclide library can reach more than 100, fully meeting the measurement needs

• Equipped with a nuclide measurement container, so that the measurement nuclide in the ionization chamber accurate positioning, reduce the measurement error

• The key automatically deducts the ambient radiation background without zero adjustment

• Implant sample, automatic measurement and range conversion, fast and accurate measurement, measuring range up to 10 curies (99mTc)

• Keyboard modification and solidification of nuclide scale coefficient without development tools

• Printable nuclide activity measurement report

• Optional remote computer Chinese Windows platform to take over the function of the activity meter operation, and can set the serial port address, scan tracing rate, data storage rate and panel nuclide name, etc
